Leaflet.VectorGrid VS mapshaper

use the vectorgrid leaflet plugin

Hi I am trying to https://github.com/Leaflet/Leaflet.VectorGrid with leaflet. I have seen that there are no typings for that project so I have created leaflet.vectorgrid.d.ts and used https://github.com/Zahma/Leaflet.VectorGrid/blob/master/leaflet.vectorgrid.d.ts as typings. I have imported both like this:

I created a demo phoenix project that shows a test page. To edit it play with the map_controller and /priv/static/map_logic.js where I added the js logic, all is done using leaflet and the vector grid plugin. Demo repository can be found tile_server

Have you thought about adding a simplification algorithm such as Ramer-Doublas-Peucker [0] or Visvalingam–Whyatt [1]? I've used https://mapshaper.org/ to do GeoJSON path simplification before and those seem to work very well. For applications which want to maintain path accuracy while reducing the number of waypoints that may be more effective than truncating the decimal places

Useing the recommended TopoJSON converter from mapshaper.org (https://learn.microsoft.com/en-us/power-bi/visuals/desktop-shape-map) however, when I add the GeoJSON file, it just freezes, nothing happens. (Does this happen to any of you?)

Have a try with https://mapshaper.org/. If you can export everything you want to "fill in" as GeoJSON, you can load in MapShaper as TopoJSON and calculate the gaps.

Look at https://mapshaper.org, and simplify the zip code file. I used the Douglas-pueker option. Should be able to get that file size down considerably. I’m a GIS person that helped some consultants put GIS data into powerbi and this worked with some of our custom data. We had 30mb files down to less than 1mb.

Transformé en fichier KML avec mapshaper.org

I have transformed the original shapefile in a geojson using https://mapshaper.org/. However, it seems that this transformation was not accurate as I have lines circling the globe as of now. See https://freeimage.host/i/H2Rt7Fp , when I load it in Python using the following code; I do however get an accurate representation:

mapshaper.org is an incredibly handy tool

yo github repo ma chucche naksa ko geojson data chha, ani yo link ma gayera shapefile ma convert garda hunchha. Malai chhai topojson chaiyeko thiyo ani yei garya thiye. Hope it helps.
